Description:A hot air balloon ride on a lovely Egyptian day — 86 degrees, sunny, light wind — turned tragic Tuesday when the balloon exploded and plummeted to the ground, killing 18 people.
It was the deadliest hot air balloon accident in the world in at least 20 years.
Tourists who have taken similar rides over southern Egypt marvel over the vantage point from the air — a beige desert valley giving way to green farmland.(0:19)
